Thanks Ashley! Jim, Albert is right - we found these washed up on the beach. We scooped out a hollow in the sand so we could see these guys floating, and I took the photo from above. They are absolutely tiny - in the second shot you can see the grains of sand floating on the surface of the water.

I checked with Nathan re the colour - wondering if it's leucistic. He thinks it's probably just about to shed. Small-eyed snakes are usually glossy black with a gorgeous rainbow sheen (like oil on water).

They're not commonly seen here either - I posted this one on a Sunshine Coast birdwatchers' page and they were all like 'whoa, is that a Dusky Honeyeater?' Michael Morcombe Field Guide says they are 'rare' south of Rockhampton but apparently the boundaries are being reconsidered.
